Comparative responses of two dominant Antarctic phytoplankton taxa to interactions between ocean acidification, warming, irradiance, and iron availability
two dominant Antarctic phytoplankton taxa ocean acidification warming irradiance iron availability
2014/10/16
We investigated the responses of the ecologically dominant Antarctic phytoplankton species Phaeocystis antarctica (a prymnesiophyte) and Fragilariopsis cylindrus (a diatom) to a clustered matrix of th...
δ13C is a signature of light availability and photosynthesis in seagrass
δ13C signature of light availability photosynthesis in seagrass
2014/4/4
We explored the role of light-saturated (carbon-limited) photosynthesis on δ13C of turtlegrass (Thalassia testudinum Banks ex König) populations from the clear, blue waters of the Great Bahama Ba...
Photoprotection mechanisms against ultraviolet radiation in Heterocapsa sp. (Dinophyceae) are influenced by nitrogen availability: Mycosporine-like amino acids vs. xanthophyll cycle
Heterocapsa sp Photoprotection mechanisms
2014/4/16
The photoprotective and acclimation capacity against ultraviolet radiation (UVR) was assessed for the
dinoflagellate Heterocapsa sp. We examined the effect of UVR and N availability on photosynthetic...
The effects of Cu and Fe availability on the growth and Cu:C ratios of marine diatoms
The effects of Cu and Fe availability on the growth and Cu:C ratios of marine diatoms
2014/4/21
We investigated the effects of copper (Cu) and iron (Fe) availability on the growth rates, cellular Cu content, and steady-state Cu uptake rates of eight species of centric diatoms (coastal and oceani...
Relative influence of nitrogen and phosphorous availability on phytoplankton physiology and productivity in the oligotrophic sub-tropical North Atlantic Ocean
nitrogen and phosphorous availability phytoplankton physiology and productivity the oligotrophic sub-tropical North Atlantic Ocean
2014/4/21
Nutrient addition bioassay experiments were performed in the low-nutrient, low-chlorophyll oligotrophic subtropical North Atlantic Ocean to investigate the influence of nitrogen (N), phosphorus (P), a...
Relative influence of nitrogen and phosphorous availability on phytoplankton physiology and productivity in the oligotrophic sub-tropical North Atlantic Ocean
Relative influence of nitrogen and phosphorous availability on phytoplankton physiology and productivity in the oligotrophic sub-tropical North Atlantic Ocean
2014/4/18
Nutrient addition bioassay experiments were performed in the low-nutrient, low-chlorophyll oligotrophic subtropical North Atlantic Ocean to investigate the influence of nitrogen (N), phosphorus (P), a...
Potential role of copper availability in nitrous oxide accumulation in a temperate lake
copper nitrous oxide accumulation temperate lake
2014/4/22
Denitrifying bacteria require copper for the synthesis of nitrous oxide reductase. In the absence of sufficient bioavailable Cu, nitrous oxide (N2O) may accumulate in natural waters during denitrifica...
Phosphorus availability, phytoplankton community dynamics, and taxon-specific phosphorus status in the Gulf of Aqaba, Red Sea
Phosphorus availability, phytoplankton community dynamics, and taxon-specific phosphorus status in the Gulf of Aqaba, Red Sea
2014/4/23
The relationships among phytoplankton taxon-specific phosphorus-status, phytoplankton community composition, and nutrient levels were assessed over three seasons in the Gulf of Aqaba, Red Sea. During ...
Iron and zinc enrichments in the northeastern subarctic Pacific: Ligand production and zinc availability in response to phytoplankton growth
Iron and zinc enrichments northeastern subarctic Pacific Ligand production and zinc availability response to phytoplankton growth
2014/5/13
Iron- and zinc-enrichment experiments were carried out at Ocean Station Papa in the subarctic North Pacific. In iron-enriched treatments, phytoplankton chlorophyll a (Chl a) increased 20-fold (9.7 μg ...
Growth rates, half saturation constants, and silicate, nitrate, and phosphate depletion in relation to iron availability of four large open-ocean diatoms from the Southern Ocean
Growth rates half saturation constants silicate, nitrate phosphate depletion relation to iron availability four large open-ocean diatoms Southern Ocean
2014/5/19
Four large, open-ocean diatoms from the Southern Ocean (Actinocyclus sp., Thalassiosira sp., Fragilariopsis kerguelensis, and Corethron pennatum) were grown in natural (low iron) Southern ocean seawat...
Responses of seagrass communities to fertilization along a gradient of relative availability of nitrogen and phosphorus in a carbonate environment
Responses of seagrass communities to fertilization a gradient of relative availability nitrogen and phosphorus carbonate environment
2014/5/19
Patterns of relative nutrient availability in south Florida suggest spatial differences regarding the importance of nitrogen (N) and phosphorus (P) to benthic primary producers. We did a 14-month in s...
Availability of iron and major nutrients for phytoplankton in the north-east Atlantic Ocean
Availability of iron and major nutrients for phytoplankton in the north-east Atlantic Ocean
2014/5/19
Because of recent findings that Fe is a limiting factor for phytoplankton activity even at relatively high dissolved iron (DFe) concentrations, the potential importance of Fe limitation was revisited ...
Light availability indirectly limits herbivore growth and abundance in a high rocky intertidal community during the winter
Light availability indirectly limits herbivore growth high rocky intertidal community the winter
2014/5/27
Light availability and consumer pressure are fundamental factors that structure aquatic communities, but their integrated effects are rarely studied in marine benthic systems. Using a factorial experi...
Iron availability, cellular iron quotas, and nitrogen fixation in Trichodesmium
Iron availability cellular iron quotas nitrogen fixation Trichodesmium
2014/6/9
Iron availability is suggested to be a primary factor limiting nitrogen fixation in the oceans. This hypothesis is principally based on cost-benefit analyses of iron quotas in the dominant nitrogen-fi...
